LC4064C-5T48C - 64-Macrocell, 5ns In-System CPLD | Lattice
MPN: LC4064C-5T48C ✓ सक्रियLC4064C-5T48C अवलोकन
A CPLD is a programmable logic device that combines a structured array of programmable logic blocks with nonvolatile configuration storage. In the product hierarchy, a CPLD is a programmable-logic semiconductor, a higher-level alternative to a fixed combinational logic implementation and a lower-complexity member of the FPGA and CPLD family. In-system programmability allows the LC4064C-5T48C to be configured or reconfigured through the system programming interface without removing it from the circuit board.
The LC4064C-5T48C provides 64 macrocells, a 5 ns propagation delay, and a maximum operating frequency of up to 400 MHz. Its I/O structure supports programmable clock polarity and up to four global clock pins, while its output architecture can address up to 80 product-term outputs. These features make the device suitable for glue logic, control logic, protocol bridging, and fixed-function logic that benefits from field configuration.
The device is identified by the manufacturer as a SuperFAST high-density PLD in the 3.3 V, 2.5 V, and 1.8 V in-system programmable family. This combination of speed, logic density, and multiple supported supply voltages provides design flexibility across embedded control, communications, industrial, and consumer systems. The manufacturer documentation describes the 48-pin package as a TQFP, while distributor records identify the same 48-LQFP package terminology.
Typical applications include bus-interface decoding, state-machine control, peripheral interconnect logic, data-format conversion, board-level timing control, and embedded system start-up sequencing. The five-nanosecond propagation-delay grade is useful where combinational decisions must be made within short system timing windows, while the 400 MHz maximum operating figure supports designs clocked at higher system frequencies subject to the device's timing constraints.
Designers should verify the exact I/O standards, input thresholds, output drive, configuration interface, and AC timing against the manufacturer datasheet for the selected supply voltage and operating conditions. PCB layout should provide a short, clean programming path, adequate ground-plane continuity, and decoupling close to the supply pins. Because this page relies on the supplied web records rather than the complete manufacturer timing tables, unspecified electrical details are marked for verification rather than inferred.
This page consolidates the verified 64-macrocell, 5 ns, 400 MHz, 48-pin TQFP, clocking, and programming attributes with distributor inventory, source links, candidate same-footprint alternatives, and application-oriented engineering guidance. That synthesis makes the LC4064C-5T48C easier to evaluate for design feasibility, sourcing, and PCB compatibility.

सामान्य अनुप्रयोग
LC4064C-5T48C के लिए उपयुक्त है 6 अनुप्रयोगs: Board-Level Control Logic, Interface and Protocol Bridging, Embedded System Sequencing, Data and Format Conversion, Industrial Timing and Interlock, Programmable Test and Measurement Logic.
Board-Level Control Logic
The LC4064C-5T48C fits board-level control logic because it provides 64 macrocells, a 5 ns speed grade, and a propagation delay listed as 2.5 ns. Designers can use its programmable logic blocks for sequencing, latch logic, state-machine decoding, and peripheral-control functions without implementing those functions in a fixed ASIC. In-system programmability allows the same PCB to support firmware-driven configuration updates or production variants. The 48-pin TQFP package also keeps the device compatible with conventional surface-mount assembly. The principal design check is to verify the manufacturer's logic-routing and I/O timing tables for every implemented path rather than relying only on the maximum 400 MHz figure.
अनुशंसित
Interface and Protocol Bridging
The LC4064C-5T48C is suitable for interface bridging when a board must translate between incompatible logic levels or combine several asynchronous control signals into a defined internal transaction. Its 64 macrocells provide a configurable implementation space, while the 5 ns grade supports short combinational delays in control paths. The indexed support for 3.3 V, 2.5 V, and 1.8 V operation is particularly useful when multiple supply domains exist, although each I/O standard and voltage combination must be checked in the complete electrical tables. In-system programming lets an equipment manufacturer adapt protocol or customer-interface variations after initial assembly without replacing the component or redesigning the surrounding PCB.
अनुशंसित
Embedded System Sequencing
For power-up sequencing and peripheral-enable logic, the LC4064C-5T48C combines 64 programmable macrocells with a 5 ns speed grade and in-system programming. It can implement deterministic state machines that generate reset release, clock-enable, chip-select, or interlock signals according to board-specific requirements. The multi-voltage family description supports systems operating from 3.3 V, 2.5 V, or 1.8 V rails, but designers must confirm I/O behavior and absolute limits. Programming the device during production or field service also reduces the need for discrete logic changes when a sequence or platform variant changes. The 48-pin TQFP format simplifies reuse of an existing Lattice footprint.
अनुशंसित
Data and Format Conversion
The LC4064C-5T48C can implement compact data-format conversion, bit-field translation, and fixed-width data-routing functions where a microcontroller or processor would otherwise require repetitive conditional code. Its programmable macrocell architecture supports configurable Boolean equations, registers, and interconnect logic, while the listed 2.5 ns propagation delay enables short combinational conversion stages. For high-throughput systems, the up-to-400 MHz operating figure provides additional timing margin, subject to the selected clock path and actual device timing grades. In-system programming allows the conversion table to be updated without removing the TQFP device, which is useful for production configuration and field-configurable industrial equipment.
अनुशंसित
Industrial Timing and Interlock
The LC4064C-5T48C is applicable to industrial timing, debounce, interlock, and safety-adjacent control logic where deterministic behavior and reconfigurability are important. The 5 ns speed grade can support short response paths between sensors, relay drivers, and monitoring logic, while the 64 macrocells allow several related functions to be consolidated. Engineers must not infer a safety certification from the availability of a fast programmable logic device; functional-safety, operating-temperature, and failure-mode requirements need separate verification. The supplied records do not provide industrial or AEC-Q100 qualification, so the exact grade should be confirmed before use in a regulated installation.
अनुशंसित
Programmable Test and Measurement Logic
The LC4064C-5T48C can serve as programmable pattern generation, trigger conditioning, timing comparison, or fixture-control logic in a compact test system. Its 64 macrocells and 5 ns speed grade are useful for combining multiple fast decision paths while retaining a single compact package and configuration file. The 48-pin TQFP provides a defined surface-mount footprint that can be reused across instrument or tester variants, and in-system programming supports rapid configuration during development. Exact I/O drive, input thresholds, and timing must be validated against the target test-node levels. The supplied data does not establish compliance with any external measurement standard, so such claims should not be made without separate evidence.

डिज़ाइन नोट्स
Treat the 48-pin TQFP footprint as the common mechanical constraint for all listed alternatives. Preserve the manufacturer-recommended pad geometry, solder-mask and paste pattern, and pin-1 orientation rather than creating a generic 48-pin footprint. Before approving a substitute, compare every configuration, power, ground, clock, and user-I/O position in the two manufacturer pin tables. A matching package name alone does not prove electrical or programming compatibility.
Route clocks and high-speed control signals with short, continuous paths and avoid splitting return current across board splits. The LC4064C family supports up to four global clock pins and programmable clock polarity, so assign clock-sensitive functions deliberately and verify the selected routing and polarity in the timing report. Keep programming and configuration traces away from sensitive analog or high-speed nets where practical, and observe the manufacturer's external component and termination requirements.
Do not equate the listed 400 MHz maximum operating frequency with the delay of every logic path. The device also carries a 5 ns speed-grade designation and a 2.5 ns propagation-delay figure; timing conclusions must use the appropriate datasheet table, supply voltage, and temperature condition. Likewise, support for 3.3 V, 2.5 V, and 1.8 V describes the family capabilities but does not by itself prove that every I/O pin can operate at every listed voltage.
अनुपालन जानकारी
The supplied web excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification status for the LC4064C-5T48C. The component is a programmable logic IC rather than a power semiconductor, so SOA is not applicable.
